This document summarizes a project on cloud computing. It divides the tasks between two members: Lam Yin Kwan covered the project background, survey and data processing, and conclusion, while Wong Weng Keong focused on data analysis, multimedia content, and PowerPoint design. The document then provides background on the history of cloud computing and defines it as internet-based services and resources. It describes the different types of clouds and models of cloud services. It also summarizes the results of an online survey on cloud computing use and perceptions. Finally, it discusses the positives and negatives of cloud computing.

6. Types of cloud
1. Public cloud

3. Hybrid cloud (combination of public and private cloud)

7. Public Cloud
1.
Is established where several organizations have similar
requirements and seek to share infrastructure so as to
appliance.
2. Service providers can make their computing resources
available online for the public.

8. Private cloud
eg. iCylanAPP
Enables you to remote access the sensitive applications of
enterprises by smart phones or tablet device anywhere and
anytime.

9. Services models of cloud computing
Platform as a service (PaaS)
Software as a service (SaaS)
Definition
 development
environments as a service
 Providing developers with
platform( server,memory,s
oftware,hardware)
application as a service to
customer
providing end users with
access to the data and
software
applications
